Bad Map Sensor N54 at Ellie Roseby blog

Bad Map Sensor N54. I'm sure these errors go together. Take it out, buy some map/sensor cleaner, clean it, put it back. Causes of 30ff fault code. The below log shows healthy afr’s on the n54 with 30% e85: I can’t remember if the one on the intake manifold or the charge pipe is the tmap but it’ll be the tmap bc of the 2f30 code. Diagnosing and repairing 30ff code. Old/worn fuel pumps or too much e85; 1) low pressure fuel pump or lpfp sensor, and running lean. I thought that unlike the maf sensor on the n55, which reads airflow, the map sensor on the n54 just reads vacuum/pressure. Plausibility implies the sensor is working but the reading is wrong vs what. This is by no means an exhaustive list of issues that may cause lean afr’s, but they are some of the more frequent causes. 2f30 and 2abd i’d imagine are likely due to a faulty map sensor. Map is pretty hard to clog, more likely dirty. Cracked or leaking piping connecting the intake, intercooler, chargepipe, bov’s, or diverter valves. This can be caused by:

Just noticed on the way home tonight my cobb monitor shows my air temp at the throtle inlet peaked at 11k.
